AbstractThe experiment was conducted during the Agricultural season 2008 in the green house of Field crops .Dept , College of Agriculture and forestry. The effect of different dosses of glyphosate (48 , 96 ,144 ,192 ml/ha) with different durations time of herbicide application after (10,20,30days) of plant clover infestation were studied . Dodder can competes strongly with clover , potentially reducing clover growth . Fresh and dry weights of dodder were decreased at the first and second durations of herbicide application . The height of plant & no . of beanches were significantly higher at the first duration whears the dry weight of stems, leaves and roots were significantly decreased as the time of application increased . On the other hand , fresh and dry weights of dodder plants were reduced as the doses of herbicide increased . Clover plant height and no . of branches were increased as the glyphosate doses increased .Dry weights of leaves , stems and roots were inversely related to the dose of glyphosate Fresh and dry weights of dodder were negatively related to the dose of herbicide at all durations of herbicide application . The results of the present study showed that glyphosate caused a cleare damage on dodder plants where as clover plants did not obtain any sign of damage had less effect on it .
